2018年4月1日 · The mass loss of grade A of TNT (pure TNT) and grade B of TNT (impure TNT) is investigated by using isothermal and non-isothermal methods. The variations of mass versus time are used for calculation of kinetic constants and activation energies.

2014年1月15日 · 2,4,6-trinitrotoluene (TNT) is a molecular explosive that exhibits chemical stability in the molten phase at ambient pressure. A combination of visual, spectroscopic, and structural (x-ray diffraction) methods coupled to high pressure, resistively heated diamond anvil cells was used to determine the melt and decomposition boundaries to >15 GPa.

2023年9月28日 · One candidate vying to replace TNT is 2,4-dinitroanisole (DNAN or DNAs). DNAN’s melting point of 92–96 °C, decomposition temperature of 226 °C and low sensitivity to external stimuli make it...

2025年3月1日 · The reason behind the published high impact sensitivity values for 2,4,6-trinitrotoluene (14 -16 J) is the solubility of air in its melt, which is enclosed in the form of microbubbles (cavities) when TNT cools rapidly (during flaking or similar processes).

2022年8月1日 · 2,4,6-trinitrotoluene (TNT), is the most widely accessible explosive. Thanks to the melt cast characteristics (melting temperature of TNT is 80-82 °C,), lead to contribute in many...

Trinitrotoluene (TNT) has been produced industrially for use as an explosive for military, mining, and demolition purposes since the beginning of the 1900s and is still used today. The continuous utility is in large part because TNT is melt castable, meaning it can be melted (80 °C) with steam and then poured

2014年7月25日 · Growth of solidification thickness and cooling temperature profiles of TNT based cast high explosive charges are predicted as functions of time and space using unsteady state heat transfer...

Many Australian munitions are filled with melt-cast TNT-based explosives such as Composition R (RDX/TNT/Beeswax 60/40/1). TNT solidifies from the melt as large, highly oriented, columnar grains. This TNT matrix contracts by about 12% on solidification, and the further contraction during cooling of the

2017年11月1日 · The kinetic and activation energy of mass loss of two grades of melted TNT explosive, grade A and grade B, with freezing points of 80.57 and 78.15 °C, respectively, were studied by isothermal and...

The kinetic and activation energy of mass loss of two grades of melted TNT explosive, grade A and grade B, with freezing points of 80.57 and 78.15 o C, respectively, were studied by isothermal and non-isothermal gravimetric methods.
